T all whom it may concern:

Be it known that I, WILLIAM H. CAPs, a

citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented a new and useful Stereotype-Plate, of which the following is a specification. v

My invention relates to stereotype-plates, and has for its object to provide a light typehigh stereotype-plate particularly adapted for newspaper and similarpurposes, said plate v being well bridged, and hence being so braced should have suflicient strength to resist strains applied thereto in removing it from the mold and to prevent distortion orbuckling during transportation; and to attain the dual advantage of lightness and strength is the main object of my present invention.

Further objects and advantages of this invention will appear in the following description, and the novel features thereof will be particularly pointed out in the appended claims.

In the drawings, Figure l is a side view of a portion of a stereotyping apparatus provided with a mold adapted to .form a pla-te constructed in accordance with my invention. Fig. 2 is an inverted perspective view of a portion of the mold. Fig. 3 is a similar View of the improved plate. Figsl and 5 are, respectively, transverse and longitudinal sections of the stereotype-plate having backs cast in accordance with my invention, and also showing corresponding portions of the molds slightly removed or displaced with relation to the plate-sections. A y

Similar reference characters indicate corresponding parts in all the figures of the drawings.

The mold l, which, however, forms no part of my present invention, is constructed of brass or other suitable material and may be used in connection with a casting-box of the ordinary construction, the same having abase.

or bottom 2 and a cover 3 and said base being provided with lateral trunnions 4:, mounted in suitable open bearings in -a supportingframe 5.

In the ordinary practice a stereotype-plate 6 is provided with main longitudinal and transverse bracing-webs or bridges 7 and 7 and auxiliary shallow connecting-webs or bridges S, between the longitudinal webs or bridges, as illustrated in Figs. 3 to 5, inclusive, the mold being provided with corresponding main longitudinal and transverse grooves or runs 9 and 9a and auxiliary connecting grooves or runs l0, inwhich said bracing-webs or bridges are formed. In order, however, to facilitate the fiowing of the stereotype metal into these main and auxiliary grooves or runs and at the same time provide the stereotype plate at intervals with enlarged bracing-webs or bridges ll, I provide a mold l with longitudinal enlarged grooves or runs l2, equal in cross-sectional area to a plurality of main grooves or runs 9 and 9a, and having flat ioors, whereby after the conclusion of the casting operation said enlarged bracing-webs or bridges may be utilized as means for displacing the plate without twisting or bending the same. These enlarged grooves or runs form suitable channels for conveying the molten stereotype metal to the grooves or runs of smaller cross-sectional area, and thus insure the proper formation of the plate.

The described construction of plate is particularly adapted for use where a plurality of columns, as two or more, are formed in one plate, and hence where the plate is of large area and after removing the plate from the mold it may, it' preferred, be divided, in the thickness of the enlarged bracing-web or bridge, by sawing the same upon the dotted line a (shown in Fig. 4) to form plate-sections.

The enlarged bracing-web or bridge is prefl erably made of a cross-sectional construction corresponding with that of the ordinary bracing-webs, the lower edge of the former being in a common pla-ne with the corresponding edges of the latter.

Various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the spirit roo or sacrificing any ol' the advantages of thc invention.

Having described my invention, what I claim is l. A stereotype-plate having its back provided With intersecting longitudinal and transverse main bracing-Webs or bridges, and an intermediate supplemental bracing-Web or bridge intersecting angularly-disposed main bracing-Webs,and exceeding the same in crosssectional area, substantially as specified.

2. A stereotype-plate having its back provided with transverse main bracing-Webs or bridges, and a longitudinal supplemental bracing-Web or bridge intersecting said transverse bracing-Webs,substantially as specied.

3. A stereotype-plate having its back provided With intersecting longitudinal and transverse main bracing-Webs or bridges, and also provided with a supplemental stiffeningweb or bridge connected with the main bracing-Webs 0r bridges and exceeding the same in cross-sectional area, substantially as specified.

4. A multiple-cple mn stereotype-plate,hav

l ing its back provided, in the planes'of tl1cdi- In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two Witnesses.
